The new Corum Admiral’s Cup Legend 46 Minute Repeater Acoustica watch comes equipped with a brand new hand-wound movement that not only includes one of the most advanced chiming complications that money (actually, really big money) can buy, but also includes into the package a pretty much impressive power reserve of at least 100 hours, which is achieved thanks to the third spring barrel reserved exclusively to the minute repeater module. Yes, that was a fairly long sentence, all right.

Judging by the looks of its rear side, the new in-house caliber Corum CO102 movement that powers this masterpiece is an extensively modified version of the gorgeous CO010 caliber that was introduced back in 2009 and powered their somewhat technocratic Admiral’s Cup Minute Repeater Tourbillon 45 model.

The new movement obviously lacks the tourbillon escapement, but in return features not one, but two pairs of gongs with the lowest-pitched pair striking hours and minutes in C and E respectively and the highest-pitched using G for the hours and C for the minutes.

As a result, the hours and minutes are coded not as single notes, but as simple chords giving your richer, more compelling sound. It will probably have a hard time rivaling monsters like Gibson Les Paul V.O.S. guitar, but will certainly give an average minute repeater a run for its money. At least, in terms of sound quality.

Just like the aforementioned Corum Admiral’s Cup Minute Repeater Tourbillon 45 watch, the minute repeater complication is activated here not by the usual slider or a push-piece on the timekeeper’s body, but with a slight turn of its signature dodecagonal bezel.

The design not only makes the watch more unique compared to its competitors, but also makes it slightly more water resistant, although it is still rated for pretty much average (within the niche, of course) 3 atmospheres.

Limited to just ten numbered pieces, the new watch is going to be offered in whole three versions. Namely, in titanium, 18-carat rose gold and 18-carat white gold with every single square millimeter of its surface set with brilliantly cut diamonds of different shapes and sizes.

As it is usually the case with watches that feature skeletonized dials or, like this one, no dials at all, the Corum Admiral’s Cup Legend 46 Minute Repeater Acoustica severely lacks in terms of visual legibility. The black open-worked hour and minute hands are simply lost among the dozens of finely crafted and decorated bridges, gears and pinions that are visible through a sapphire crystal that protects the precious mechanism from dust and moisture.

Still, with such an advanced minute repeater mechanism gently hugging your wrist, you don’t really need any visual readability. In fact, even a blind person can use it quite comfortably to get all the data he or she needs. Actually, to use the repeater efficiently, all you need here is to learn its not particularly sophisticated time-telling code and you will always be able to check time in style.
